90080 ÷ 83 
We're looking to find how many times 83 goes into 90080.

Let's proceed to step 1:
When dividing 9 by 83, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 83

On to step 2:
If we divide 90 by 83, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 83 away from 90, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 83

Advancing to step 3:
70 divided by 83 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 70 to get 70.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 83

Step 4:
83 can be fit into 708 8 times, resulting in a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
If we subtract 664 from 708, we get 44.
Append the next digit (0) from the dividend to 44 and continue with: 440 / 83

On to step 5:
The number 83 fits into 440 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1085.0
If we subtract 415 from 440, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 6:
The number 83 fits into 250 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 1085.3
Subtract 249 from 250 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 83, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1085.3
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 83, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1085.301
Deduct 83 from 100 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
83 goes into 170 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1085.3012
Subtracting 166 from 170 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
The number 83 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 1085.3012
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
If we divide 400 by 83, we get 4 and a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 1085.301204
Deduct 332 from 400 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 12:
The number 83 fits into 680 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 1085.3012048
Subtract 664 from 680 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
The number 83 fits into 160 1 times, leaving a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 1085.30120481
The remainder is 77 after subtracting 83 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The final outcome is 1085.30120481, with a leftover of 7.7e-08.
